Which of the following is the most effective example of a thesis statement? a. the main causes of global warming. b. what are the main causes of global warming? c. the main cause of global warming is human behavior. d. global warming.

I think the answer i c. The answer a. would be in the paragraphs explaing the causes of global warming, not in the thesis statement. b. it seems more of a question for a thesis statement then an explination so therefore i think that would be in the paragraphs supporting a thesis statement rather than in a thesis. And d, just saying global warming isnt a thesis, nor is it effective. Just saying global warming and thats it is dull, and that is more a title. That is why I say the answer is c. Have a great day, I hope this helps, and please correct me if im right or wrong, i do apreciate feedback on whether im right or wrong to better help my answering in the future. :)
